ABSTRACT:
The present invention is a bone fixator for repairing fractures of the distal radius and wrist. It includes, in the preferred embodiment, at least two generally parallel, spaced-apart elongate distal mounting pins with lower ends for mounting in the metacarpal bone and at least two generally parallel, spaced-apart elongate radial mounting pins with lower ends for mounting in the radius. A distal pin clamp assembly secures the distal pins to an elongate distal member. The clamp assembly and pins are movably coupled to the distal member for translational movement along its elongate axis and pivotal motion about a pivot axis generally perpendicular to the elongate axis of the distal member and the elongate axes of the distal pins. A pin mounting carriage holds the radial pins and an elongate medial assembly is connected at one end to the pin mounting carriage for independent translational motion along an axis generally perpendicular to the elongate axes of the proximal mounting pins and the elongate axis of the medial assembly and coupled at the opposed end through a ball joint to the distal member.
